Function Documentation

abort_default()

void SymPrefix abort_default ( MPI_Comm comm, const char * msg, const char * source, int line )

extern

This function prints the message argument and file and line of the error to standard error, and calls either MPI_Abort or abort depending on whether MPI is initialized.

Parameters

comm	MPI communcator object to use on call to MPI_Abort
msg	message text to print
source	string describing source file name
line	line number of caller
